1. Central Receiving Colorado State University Ergonomics Frank Gonzales Risk Management Ergonomics Program Coordinator

2. Why Are You Here? Injury Prevention SafetyErgonomics

3. Agenda Introduction Ergonomics & Safety Concerns Discussion Trivia –Game Injury Risk Factors Lifting Group Demonstration Misc Topics

4. Introduction Break into groups As a group discuss ergonomics & safety related concerns that you have with your job Write down on paper Discuss with class after ~5 minutes 4

5. Example - Ergonomics Conveyor system Reduced bending Ideal height of ~30” above floor

6. Two Teams Buzz your buzzer if you know the answer If incorrect, opposing team gets one answer attempt If incorrect, no points for either team Team points added up

7. What Does “MSD” stand for? QUESTION 1

8. A. Metro Storage District B. Musculoskeletal Disorder C. Macromolecular Structure Decision D. Master of Science In Design QUESTION 1

9. Answer A. Metro Storage District B. Musculoskeletal Disorder C. Macromolecular Structure Decision D. Master of Science In Design

10. Injury Risk Factors Break into 2 groups –Each group compiles a list of as many risk factors pertaining to their job as possible –Write on board after ~5 minutes

12. OTHER RISK FACTORS for MSD’s Contact Stress Cold/heatVibrationNoise Physical Stress Emotional Stress Etc

13. Same Groups One new person from each team comes up to the front Question pops up on screen Buzz your buzzer if you know the answer 1 pt for each correct answer

14. Which Is Most Likely to Create a Back Injury? A.B.C. 14

15. ERGONOMICS CONTROL STRATEGIES 15

16. Engineering Controls Eliminating the Problem –Ideal! Sometimes difficult to implement Ergonomics is not back safety training alone…it is removal of the lift. 16

17. Administrative Controls Job rotation –Switching tasks/job Training –Body Mechanics Awareness of lifting & safety techniques Do’s and don'ts 17

18. Equipment Operator Materials Handler Sorting Boxes/Packages –Repetitive –Heavy Lifting –Awkward Bending –Grasping Boxes/Packages Duration, intensity, frequency can be high –Increase risk for injury

19. Wrist Deviation (Awkward Posture) 25°, 80% 45°, 75% 0°, 100% 45°, 75% ULNARRADIAL EXTENDEDFLEXED 0°, 100% 65°, 45% 45°, 60%

20. Reduce Grip Force Pick up smaller loads Use carts and/or hand trucks Keep tools in good working order Keep your wrists straight Wear correct type of gloves

21. Which MSD can this posture potenially lead to? QUESTION

22. Carpal Tunnel Syndrome Most common cause (risk factor): –Pinch grip with wrist flexion Other causes –Obesity –Gender –Age –Smoking –Etc 22

23. Demonstration - Lifting In your groups take 10-20 minutes to discuss the lift you have been assigned. Prepare for demo & discussion Group 1 demos kneel lift/tripod lift –Also discuss how this can be used in the job Group 2 demos golfers lift –Also discuss how this can be used in the job Group 3 demos power lift –Also discuss how this can be used in the job

24. Tripod Lift One knee on the floor for balance.

25. “Golfer’s Lift” 25

26. Power Lift Most powerful lift Item is positioned between 30-50” from floor Muscles are slightly contracted providing most strength

27. Avoiding the Lift Stickers on side of boxes –Easy and quick scanning –Less lifting to reach bar code –Time Save & Back Saver! 27
